摘要

This paper puts forward to a geometric preprocessing model based on differential GPS (DGPS) and inertial measurement unit (IMU) data for airborne SAR image. Firstly, the DGPS/INS data are preprocessed to determine the SAR antenna centroid and platform attitude. Secondly, relative to SAR navigation coordinates system, observational coordinates of the radar images are calculated. Finally, after strip adjustment, the geometrically preprocessed SAR image or SAR ortho-image based on DEM are obtained. The correctness of mathematic model is verified with the results of test area in western part of China. Finally the main systematic error sources are analyzed and their correction method is presented.
